Researchers usually employ orthogonal arrays or D-optimal designs with little or no attribute overlap in stated-choice surveys. The challenge is to balance statistical efficiency and respondent burden to minimize the overall error in the survey responses. This study examined whether simplifying...

Willingness-to‐pay (WTP) estimates derived from discrete‐choice experiments (DCEs) generally assume that the marginal utility of income is constant. This assumption is consistent with theoretical expectations when costs are a small fraction of total income. We analyze the results of five...

Background: Patient preferences can affect colorectal cancer (CRC) screening test use. We compared utility-based preferences for alternative CRC screening tests from a stated-preference discrete-choice survey of the general population and physicians in Canada and the United States. <P>Methods:...</p>

The development of mutations associated with resistance to antiretroviral therapy (ART) has been shown to be a major cause of treatment failure in patients infected with HIV-1. These resistance mutations can be assessed by a genotyping test that probes for specific mutations within the HIV...

Health and environmental economists have been employing Stated-Preference (SP) methods such as conjoint analysis or contingent valuation to estimate the monetary value of public health interventions and environmental goods and services. However, the quality of data and the validity of results...

Despite the increased popularity of conjoint analysis in health outcomes research, little is known about what specific methods are being used for the design and reporting of these studies. This variation in method type and reporting quality sometimes makes it difficult to assess substantive...

Decisions regarding the development, regulation, sale, and utilization of pharmaceutical and medical interventions require an evaluation of the balance between benefits and risks. Such evaluations are subject to two fundamental challenges—measuring the clinical effectiveness and harms...

"We examine the effect of giving respondents time to think about their stated choices (SC) in a survey of cholera and typhoid vaccine preferences in Hue, Vietnam. Because neither vaccine is widely available in Vietnam, we used the SC approach (a stated preference technique) and gave half of our...
